Study of the effect of non-zero external conditions on QCD phenomenology
within the holographic approach
A.D. Katanaeva
The bottom-up approach to the holographic AdS/QCD (anti-de Sitter/Quantum Chromodynamics) correspondence, which is a new tool to investigate QCD nonperturbatively, is considered.
Getting of the full phase diagram of QCD matter as a function of temperature and baryon chemical potential is a major problem both for theoretical physics and experimental researches.
Author uses methods of AdS/QCD approach to bring out the phase structure of several holographic models in which transition to a deconfined phase is related to a (first order) Hawking-Page phase transition. The way input phenomenological and theoretical model parameters affect predictions of the value of the critical temperature and chemical potential is studied in detail.
Comparison of model predictions with results of experimental investigations, lattice QCD simulations and other methods is done. Concordant results are received in many cases. This can be rated as another success of holographic models in application to physical systems.
